Resumen
The sheep meat market in Brazil grows every year always with high added value. But there
are few reports that focus on the description and pathological characterization of gross
alterations found during sheep slaughter for guiding professionals about the final diagnosis
and proper disposal of altered tissues and carcasses. Considering this lack of information, the
aim of this work is to characterize macro and microscopically the lesions in tissue samples
collected during sheep slaughter in a slaughterhouse in Southern Minas Gerais and, if
possible, to identify the diseases associated with these lesions, as well as correlating the
findings with published data of sheep diseases, especially in the Southeast Brazil, where
sheep farming is a relatively new activity. Samples with gross alterations of different tissues
and organs of sheep carcasses were collected from a slaughterhouse with Federal Inspection
service in Southern Minas Gerais. The inspection of sheep carcasses followed the Regulation
for Industrial and Sanitary Inspection of Products of Animal Origin. The samples were
collected by federal inspectors, fixed in 10% formalin, and sent from July to October 2019 to
the Sector of Veterinary Pathology, Department of Veterinary Medicine, Faculty of Animal
Science and Veterinary Medicine, Federal University of Lavras, for macroscopic evaluation,
histopathological processing, and microscopic analysis. A total of 283 tissue samples from
sheep deriving from 21 municipalities in the state of São Paulo, Minas Gerais and Espírito
Santo were evaluated. With respect to the sex and age of the animals, males younger than one
year were predominant. Of the 283 samples, the three main organs referred were lung, lymph
node and liver. The most frequent histopathological diagnoses were chronic
bronchointerstitial pneumonia (34.76%), caseous lymphadenitis (24.39%), eosinophilic
granuloma (16.77%), and cysticercosis due to the larval form of Taenia hydatigena (7.93% of
the diagnoses). The gross and microscopic characterization of the alterations found in the
slaughter line is important as a subsidy for professionals who work in the inspection line, as
they allow reducing the risk of misdiagnosis, erroneous disposal, and, consequently, reducing
financial losses for slaughterhouses and sheep producers. Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) The sheep meat market in Brazil grows every year always with high added value. But there
